As explained on the page, "How Chinese Medicine Works" the herbs with the exact opposite energy of the patients particular organ system (element) are used to achieve balance and wellness. Also if you read about The Three Tresures  you will see just what these herbs are addressing!

In the case of the water element (kidneys and reproductive system) most imbalances are usually of a deficient nature. Sometimes deficient yin, sometimes deficient yang and sometimes both. Sometimes a person will have an excess of either yin or yang and very rarely, an excess of both! If someone even had just a good balance of both they would, among other things, have a very healthy sex drive!

The water element  carries the "Jing" or essence of life. The Jing is the most important pattern in our bodies, carrying with it, our development and our reproductive energies.  Through the use of herbs such as blood tonics, chi tonics Kidney Yin and yang tonics, est. the body’s jing is amplified and supported.

How it all began centuries ago:  

Through the centuries Chinese herbal doctors would occasionally see a patient with the  "Rare Excess of Both Kidney Yin and Kidney Yang". Many of these patients would "live for sex". (We have a lot of colorful names for these people today)  The Chinese Doctors found this overindulgence in "affairs of the bedroom" to be un-healthy, injuring the Jing, and resulting in lumbago, dizziness and general weakness of vitality.

One of the doctor’s choices would be to encourage the patient to have less sex! ( Never a popular request! ) Besides, to reduce both the yin and yang of the jing could be harmful and there are really no safe herbs to do this! (There are only herbs to bring up the yin or yang of the kidneys to correct the deficiency)

So over the centuries many doctors would have to find a way to re-harmonize the patient, (along with there spouses) by building up the chi and blood flow of the jing so he and she could sustain a high amount of sexual activity. 

This is how and why the "Sex Tonics" were born. It was not out of lust! They also discovered that an enriched sex life between couples brought more harmony and happiness (along with good health) now that they could sustain it.

 Are these tonics good for us?

A very interesting discovery also happened in the fact that many of those who took these tonics achieved a very long life, good eyesight and healthy beautiful skin through there old age.

Longevity was much prized by the Chinese and with the "side effect" of beautiful skin, good eyesight and strong sex energy, these tonics were much in demand by the wealthy. The emperors (Many with 30-50 wives) and governors and high society paid a large price for these tonics who's formulas we're kept secret by the enterprising herbal doctors.

In short, when you bring the kidney yin and yang up to the max and support it with chi and blood moving tonics and blend all these herbs with specific male or female jing-essence herbs, you have built a stronger jing channel which not only gives us more sexual energy, pleasure and desire but more of all the vital essences of life!

About The Herbs Of These Three Sexual Enhancement Formulas:

The three sexual tonics: "Blissful Jing For Her", "Blissful Jing For Him" and "Jing Essence" (All designed here at Plant Cures) were born out of years of research into the centuries of Chinese tonic herbs for long life, enriching Chi, promoting blood flow and most importantly for  products such as these, building sexual pleasure, desire, and enhancing the jing channels.

We start with a base of plants that brings the kidney yin and yang up to a very high level for both men and women. This group contains the herbs: Tien Men Dong, Rou Cong Rong, Ji Li, Yin Yang Huo, Suo Yang and others. Yin Yang Huo (Sexual Goat Plant) was named from observing goats that ate this plant. They became very sexually active! This first group uses the same herbs for males as for females. ( It is, after all, testosterone that helps do the trick of orgasm in both males and females!)

The Kidney Yang tonics stimulate the fire of the kidneys to produce a strong sexual drive. These tonics are a known group of true aphrodisiacs and are extremely effective. They promote good circulation in the sex organs and are known for their ability to increase semen in men and to increase sexual fluids in women by warming the female genitals increasing sensitivity. They also nourish and calm the heart and nervous system producing a feeling of relaxation and freedom.

The Yin tonics are nourishing, nurturing and moistening to the tissues and fluids and are used together with blood tonics, supporting each other's function. If the kidney Yin is abundant then so is the sexual energy.

 The other parts of the two formulas are blood tonics such as Dong Gui which tends to "supercharge" the jing. Also there are chi tonics and blood movers like Achyranthes Root.
